The energy audit and subsequent upgrades transformed the farm’s irrigation system, delivering substantial financial, operational, and environmental benefits. Replacing inefficient line shaft pumps with modern submersible pumps, coupled with the strategic use of Variable Speed Drives, significantly improved system efficiency and reduced electricity consumption. The integration of 40kW solar arrays further enhanced energy savings, cutting costs and lowering reliance on grid power.
Collectively, these measures resulted in an annual energy reduction of 123,146 kWh—a 72.5% decrease—while lowering greenhouse gas emissions by 99.7 tonnes of CO₂ annually. The upgrades not only addressed the inefficiencies of the ageing system but also positioned the farm for long-term sustainability and cost-effectiveness.
This project highlights the importance of tailored energy solutions, demonstrating how targeted investments in efficiency and renewable energy can meet the dual goals of reducing operational costs and improving environmental outcomes. It serves as a blueprint for other agricultural operations seeking to enhance productivity while promoting sustainability.
